DOOR .AND CUSHION THEREFOR.

Application led August 11, 1926. Serial No. 128,579.

This inveiition relates to doors and cushions therefor and finds aparticular application to the doors of closed vehicles. In the preferredembodiment of the invention herein shown as an example thereof I providemeans in connection with an automobile door which serves as a gasket formaking the door weather-tight and also as a bumper and as asound-deadener.

My invention will be well understood by reference to the followingdescription of an illustrative embodiment thereof shown by way ofexample in the accompanying drawings. wherein:

Fig. 1 is a perspective view of the body of a closed vehicle havingcushions embodying my invention applied to the doors thereof;

Fig. 2 is a section through the forward corner post. of the vehicle andthe adjacent portion ofthe door closing thereagainst but on a largerscale;

Fig. 3 is a view similar to Fig. 2, omitting the door and showing thepost and the cushion in separated position; and

Fig. 4- is a section through the corner post showing a modified methodof fastening.

I have herein shown my invention as applied to a closed vehicle of thetype illustrated and described in the patent to IV illiam ll-l. Edmond,No. 1,570,560, dated Jan. 19, 1926. Referring to Fig. 1, the vehiclecomprises a lower body portion 5 from which rise top-supporting partssuch as the forward corner posts 7 and other posts 9 which form a partof a door case and are provided with flanges 11 forming stop sur facesfor the upper portion of the door. The door which is received in thecase may embody, as described in said patent, a lower door section 13extending between the Sill and the belt line and which may be hung iuany suitable or customary manner while the upper portion of the doorconsists of a frame 15 in which the glazing17 (Fig. 2) slides. As shownin Fig. 2, the frame 15 may have a suitable clearance at the sides fromthe adjacent posts such as the posts 7 illustrated in that figure sothat there is no contact between these arts which could cause squeaks orrattles. ln the preferred formof my invention shown the stop flanges 11and the corresponding stop flange for the upper crosspiecey or lintel ofthe frame 15 may be provided throughout their length with a suitablecushion denoted generally by the numoral 19 against which the frame 15closes and which serves in the manner of a gasket to form aweather-tight seal throughout the periphery of the f ame. The formof,cush ion 19 herein shown by way of example comprises a strip of lightmetal channel 21, the web or base of which may rest flat upon the faceof the stop flange 11 and provides for the engagement with such base ofmechanical securing means for securing the cushion as a whole to theflange 11. The channel may have inturned flanges 23 which retain a body25 of resilient material such as rubber, the central portion of whichmay protrude markedly outwardly beyond the channel which contains it tobe presented to the surfaces of the door which close toward the stopflange, the door contacting solely with the rubber body 25. This rubberbody may be in the form ofa suitable molded strip and may convenientlybe provided with a central opening 27 which increases the yieldingquality thereof. The protuberant central portion is thus disposedsomewhat in arched formation so that under compression by the door theedge portions tend to be pressed firmly into their seats in the inturnedflanges 23.

The rubber body 25 may also serve to cover the fastening means by whichthe cushion is secured to the stop flange. In Figs. 2 and 3 I have shownfastening means which are in the nature both of snap fasteners and ofrivets. This means of fastening finds a particular application to thetype of post 7 which is illustrated which is stamped from suitable sheetmetal, the stop flange 11 eing formed by folding onc'edge of the blankaround the other edge, as illustrated, to form a flange portioncomprising three thicknesses of sheet metal. The fastening means hereinshown takes the form of a suitable double-headed button carried by thechannel 21 and having a retaining head 29 resting against the interiorof the web thereof and having a suitable resilient head 3l analogous toa glove fastener projecting from the rear thereof. Referring to Fig. 3,the outermost thickness of the flange 11 ma be formed (convenientlyprior to the ben ing of the post to shape) with an opening 33 of suchsize as to permit the head 31 to be pressed past the margin thereof andto sna i into position the head expanding behin the margin of theopening. To permit this action the central thickness of the flange maybe provided with a larger or Vclearance hole 35. In the preferredembodiment of the invention shown the parts are so proportioned that onpressing the cushion home the head 31 will make contact with theinnermost thickness of the flange which will serve to upset the same,riveting it over in the space provided by the hole 35 and over the marin of the hole 33. It will be understood t at fastening means ,may beprovided at suitable intervals to provide for proper anchoring of thecushion in accordance with the requirements of the particular case.

In Fig. 4 I have shown the cushion 19 as attached to the post 7 by meansof a screw 37 extending through the flange 11 and tapping into the webof channel 21. This screw may have the general form of a wood screw withcase-hardened threads, beine' what is known as a self-ta ping screw, andmay engage the metal o the channel 21 without any preliminarypreparation of the latter.

The rubber 25 may readily be renewed if worn or the channel whichcarries it can easily be torn ofl' and a new cushion substituted. Thecushion as conveniently applied may rest flat against the stop flange 11and the door presses directly against the same and tends to hold it onits seat without any twisting or tearing strain on the rubber or on thefastening means therefor. The securing means are covered by the rubberand under ordinary wear there is no danger of their coming into contactwith the door frame and causing noise or marring of the same.

The cushion comprising the base of the channel strip 21 and theresilient body 25 may be supplied in long lengths and utilized in suchlengths as desired. In the example shown the stop surfaces of the entireupper portion of the door casing are lined with such strip providing acontinuous gasket against which the door closes, making a weather-tightjoint all the way around.

I have described in detail one particular embodiment of my inventionshown by way of example in the accompanying drawings.
